A MINIATURIZED REACTOR FOR PHOTOCATALYSIS AND FOR SIMULTANEOUS IN-SITU SPECTROSCOPY

The design of a miniaturized photoreactor is presented that allows for continuous as well as for stopped flow photochemical experiments on s olid photocatalysts with gaseous educts. Volatile products can be anal yzed by any gas phase detection scheme such as mass spectrometry or ga s chromatography. In addition, the design allows for easy in situ opti cal spectroscopic measurements such as UV/VIS, IR, and luminescence, d epending on the transparency of the window material used.
